In warm-weather months, the Penn’s Landing waterfront area along the Delaware River is always busy with activity. On the Great Plaza there are ongoing free festivals, summer concerts, a movie series, and Fourth of July fireworks. Other attractions here include the RiverLink Ferry to New Jersey, the Independence Seaport Museum, and kayaks and swan boats available for rental. In winter, Penn's Landing is host to one of Philadelphia's most spectacular outdoor ice rinks, the Blue Cross RiverRink. Historic ships, including the Moshulu, a beautiful 1904 four-masted steel sailing vessel, are moored at the waterfront. The Moshulu now features a popular restaurant on its deck, and the tall ship is dramatically illuminated at night.
